Observations when Acetic Acid is placed on Litmus Papers
Blue Litmus Paper:
- When a drop of Acetic Acid is placed on a strip of blue litmus paper, the blue color of the paper turns red.
- This indicates that the Acetic Acid is an acid and can lower the pH of the solution it is placed in.
- Acetic Acid reacts with the basic nature of the blue litmus paper, resulting in the change in color.
Red Litmus Paper:
- When a drop of Acetic Acid is placed on a strip of red litmus paper, there is no change in color.
- This indicates that Acetic Acid is not a base and does not have a high enough pH to react with the red litmus paper.
- Red litmus paper is used to determine if a solution is acidic or neutral. If the red litmus paper remains red, it means the solution is acidic.
Explanation
Litmus paper is used to determine if a solution is acidic or basic. Blue litmus paper turns red when placed in an acidic solution, while red litmus paper turns blue in basic solutions. Acetic Acid is a weak acid that has a pH of around 2.5. When placed on a strip of blue litmus paper, the blue color of the paper turns red, indicating that the solution is acidic. This occurs because Acetic Acid reacts with the basic nature of the blue litmus paper and lowers the pH of the solution.
On the other hand, when placed on a strip of red litmus paper, there is no change in color. This indicates that Acetic Acid is not a base and does not have a high enough pH to react with the red litmus paper. Red litmus paper is used to determine if a solution is acidic or neutral. If the red litmus paper remains red, it means the solution is acidic.
In conclusion, observing the changes in color of litmus paper when Acetic Acid is placed on it can help determine the acidity or basicity of the solution. Blue litmus paper turns red in acidic solutions, while red litmus paper turns blue in basic solutions.

When acetic acid is placed on the strip of blue litmus paper then the blue litmus paper changes into red colour because the acetic acid is an acid so it change blue litmus to red.
When acetic acid is placed on the red litmus paper ther will be no colour change because acetic acid is an acid and it had no colour change in red litmus paper.
